A:Answer While I have not seen nor have I used the "regular" version, I do have the turbo. It is so quiet, you can't hear it. I purchased it primarily for the use of dust, allergens, pet (dog) related dander, shedding, smells, and the square footage coverage (500 sq.). I can say it has made 100% difference in all things I mentioned. It is easy to clean and no replacement filters needed.
